Nevoid Hypertrichosis
Nevoid hypertrichosis (pronunciation: nee-void hy-per-tri-cho-sis) is a rare medical condition characterized by excessive hair growth in an area of the skin where hair does not normally grow.
Etymology
The term "nevoid hypertrichosis" is derived from three words: "nevus," a Latin word meaning "birthmark" or "mole," "hyper," a Greek word meaning "over" or "excessive," and "trichosis," a Greek word meaning "hair."
Definition
Nevoid hypertrichosis is a condition where an individual has excessive hair growth in a localized area of the skin. This condition is usually present at birth or develops shortly after. The hair growth is not associated with any other abnormalities and the underlying skin appears normal.
Symptoms
The primary symptom of nevoid hypertrichosis is the presence of excessive hair growth in a localized area. The hair can be any color, but is often darker than the surrounding hair. The hair growth is usually limited to one area, but multiple areas can be affected in some cases.
Causes
The exact cause of nevoid hypertrichosis is unknown. It is thought to be a genetic condition, but the specific genes involved have not been identified. It is not associated with any other medical conditions or syndromes.
Treatment
Treatment for nevoid hypertrichosis is not usually necessary, as the condition is not harmful. However, some individuals may choose to have the hair removed for cosmetic reasons. This can be done through methods such as laser hair removal or electrolysis.
